19 inch CGA-EGA-VGA-SVGA LCD arcade monitor
Quantity Left: 0
Have had two shops test my main board and both said it performed perfect at their facilities. Then installed a new 19â€ LCD monitor with board and power supply and still have almost the same problem I had with the original monitor/chassis (attachments show original and new monitors). Have replaced the Z80 chip, added twobits.com SuperABC kit, and tried to â€œresetâ€ the 44 pins in the original main board edge connector. Have no audio and no movement. Tried test mode and play mode but get same screen.
